Features of PK Models （Single-type variable-pitch pulleys）

These are VARI-DIA pulleys that use wide speed-change belts. They are used by mounting them on motors.Use of wide speed-change belts provides larger speed-change ratios, ensuring very large transmission capacity. There are six sizes of compatible motors, ranging from 0.4 kW (4-pole) to 18.5 kW (6-pole).
